Simple calendar question with apparent no answer
Looking into an issue where no matter what I try, calendar will not delete a "birthday" that is the wrong date (have given up; the correct date is there, gmail has the correct date, apple mail contacts has the correct date, but the incorrect one is permantly in the calendar. No clicking, unclicking, choosing calendars, required. No incorrect calendar, calendar is chosen, have done all that, there is no suggestion I'm sure that works.) Moving on.
In the meantime, I discovered the "chinese" and "Sydney Australia" delegates of Weather on my account. Apparently they are all good friends as well.
Open/close, changes to [insert random weather page here]. I can share, save, cuddle, make into a friend, read about it, check info, but apparently there is no F'ing way to get rid of it.
What's the deal?
I don't want to spend days and hours reading 1000s of scripture.
What is it?
How to I get rid of it?
